“…However, it still takes days to control the target pest. [14][15][16][17][18][19][20][21] It has been reported that MB and PH 3 mixtures exert synergistic effects on stored product pests, such as Sitophilus granaries and Tribolium castaneum, 22,23 therefore we hypothesized that fumigation with MB and PH 3 mixtures could have potential for postharvest control of fruit flies. In the present study, we tested the efficacy of short-period fumigation (2.5 h) with PH 3 and MB gaseous mixtures at disinfesting B. dorsalis, and evaluated the post-treatment quality of Nanfeng mandarin fruits.…”

BACKGROUND Chinese Nanfeng mandarin (Citrus reticulate Blanco ‘2–6’) fruit is host to the oriental fruit fly Bactrocera dorsalis Hendel, and therefore requires phytosanitary treatment before exporting abroad. The use of methyl bromide (MB) should be reduced because it has phytotoxic and ozone depleting properties. In the present study, fumigations with mixtures of gaseous phosphine (PH3) and MB were conducted to disinfest B. dorsalis. The effect of combined fumigation on postharvest quality of Nanfeng mandarin fruit was then evaluated. RESULTS There was a clear synergistic effect between MB and PH3 against B. dorsalis at 20 °C. The third‐instar larvae of B. dorsalis were the most tolerant to treatment with both MB alone and combined with PH3. Toxicity assay of third instars indicated that higher PH3 concentrations increased MB toxicity, and 1.42–2.84 g m−3 of PH3 was optimal when combined with MB. Probit analysis showed that, combined with 2.13 g m−3 PH3, similar mortality was achieved with 50% of the MB required when applied alone. Furthermore, the fruit quality test showed that MB fumigation resulted in a higher respiration rate and >40% fruit rot after storage. The combined treatment reduced these effects and did not have adverse effects on fruit firmness, soluble solid content, titratable acidity, or vitamin C content. CONCLUSION Our findings demonstrate the synergistic effect between PH3 and MB and indicate that this treatment has potential as a novel strategy for postharvest control of B. dorsalis, especially in MB‐sensitive fruit. © 2019 Society of Chemical Industry

“…Generally, PH3 fumigation has been used to control insects affecting agricultural products requiring lowtemperature storage conditions for fresh preservation (Jamieson et al 2012). In this case, scale insects (mealybugs) can be controlled by fumigation with about 3000 ppm PH3 gas for 36 h at 1-3°C.…”

“…In this case, scale insects (mealybugs) can be controlled by fumigation with about 3000 ppm PH3 gas for 36 h at 1-3°C. Currently, ECO2FUME (Cytec Industries Inc., West Paterson, NJ, USA), a mixture of 2% PH3 with 98% CO2, is used commercially for the disinfestation of stored products and nursery trees in quarantine facilities (Jamieson et al 2012;Moon et al 2012). However, the control efficacy of PH3 fumigation is known to be higher at higher temperatures than at lower temperature (Liu 2008).…”

Heating is one of the many disinfestation methods commonly used in facilities that store and process agricultural products. In this study, we have investigated whether the combination of heat treatment with diatomaceous earth (DE), phosphine (PH3) or CO2 affects the mortality of the wandering larvae of Plodia interpunctella, which is a major pest found in most stored agricultural products. The mortality rate was 35.0% at day 1 after heat treatment at 40°C for 6 h; however, mortality rates increased after combined treatments of heat and 1 ppm DE or 10 ppm PH3, while 10% CO2 had no significant effect. Quantitative real‐time PCR analysis showed that combined treatments involving 1 h of heat treatment with either DE, PH3 or CO2 increased the mRNA levels of four heat shock protein (hsp) genes (hsp25, hsp70, grp78 and hsp90) in wandering larvae, 1 h post‐treatment, although those rates were slightly differentiated in each heat shock protein. Our results demonstrate that combinations of heat and DE or PH3 show increased lethality, although insects produce stress responses at the molecular level.

“…These larvae were pink, not laccid, but only capable of slight movements and when these barely alive larvae were examined 10 days after treatment, most remained moribund. While appearing to be near dead, as discussed by Jamieson et al (2012), a phytosanitary inspector will justiiably determine moribund larvae to Figure 1 Mortality (mean ± SEM corrected for control mortality) of ifth instar codling moth larvae within apples exposed to different phosphine concentrations for 48 or 72 h at 0.5 or 12°C.…”

“…Phosphine has a long history as a product for disinfesting grain (Chaudhry 1997) and recently has been used as a pest mitigation treatment at cool-storage temperatures for a wide variety of fresh produce in Chile (Horn et al 2010) and for kiwifruit in New Zealand (Jamieson et al 2012). An eficacious fumigant against codling moth could replace methyl bromide for the Japanese market and facilitate access for New Zealand apples to other countries where codling moth is not present.…”

Codling moth although rare on New Zealand export pipfruit is a quarantine actionable pest that limits access to countries where it is not present and requires specific control measures during production Fumigation with phosphine gas is a disinfestation technology that has recently been extended to fresh produce Apples infested with codling moth fifth instar larvae and eggs were fumigated for two durations at concentrations from 500 to 3500 ppm phosphine at two temperatures Larval mortality assessed 3 days post fumigation at 05C increased with increasing dose with little difference between 48 and 72h treatments In contrast mortality after fumigation of larvae at 12C did not increase with dose and resulted in overall higher mortality than 05C Codling moth eggs were more susceptible to fumigation at 05C than at 12C; fumigation at 12C had minimal effect at all doses The implications for improved market access using phosphine fumigation are discussed
